OBJECTIVE: Elevated expression of the ROR1 and ROR2 Wnt receptors has been noted in both the tumour and stromal compartments of ovarian cancer patient tissue samples. In vitro studies have suggested these receptors play a role in ovarian cancer metastasis. However, these previous studies have utilised simple 2D in vitro models to investigate cancer cell growth and migration, which does not allow investigation of stromal involvement in Wnt driven metastasis. AIM: To investigate targeting ROR1 and ROR2 using a primary co-culture 3D model of epithelial ovarian cancer dissemination to the omentum...

Mesenchymal stem cells (MSCs) have been reported to localize in colorectal carcinomas, and participate in the formation of the tumor microenvironment. They have recently been isolated from colorectal cancer tissues, and are implicated in the growth, invasion, and metastasis of cancer cells. However, the roles and detailed mechanisms associated with human colorectal cancer-derived MSCs (CC-MSCs) have not been fully addressed. In this study, we found that CC-MSCs increased the migration and invasion of colorectal cancer cells and promoted the tumorigenesis of colorectal cancer through epithelial-to-mesenchymal transition (EMT) in vitro...

MicroRNAs (miRNAs) have been extensively studied over the decades and have been proposed as potential molecular targets for cancer treatment. Studies have shown that miR-378 participates in numerous biological processes in various cancers; whereas miR-1827 has only been reported in pediatric glioma. The mechanism of how miRNAs modulate lung cancer metastasis remains unclear. Our previous study demonstrated that miR-378 is up-regulated while miR-1827 is down-regulated in high invasive lung cancer sub-cell lines, and their biological functions have been described...

Lymph node metastasis (N classification) is one of the most important prognostic factors of nasopharyngeal carcinoma (NPC), and nerve involvement is associated with the transition of the N category in NPC patients. Although the nervous system has been reported to participate in many types of cancer progression, its functions in NPC progression remains unknown. Through analysis of gene profiling data, we demonstrate an enrichment of genes associated with neuronal development and differentiation in NPC tissues and cell lines...

Background: Thyroid cancer is the most commonly reported endocrine malignancy, and its increased incidence has been the highest in all human tumors in recent decades. To investigate the mechanism of papillary thyroid cancer (PTC) occurrence and progression, we performed RNA sequencing and found an upregulated gene, LAMB3. However, the biological function of LAMB3 is still not clear. Materials and methods: We analyzed LAMB3 expression using The Cancer Genome Atlas (TCGA) database and hypothesized LAMB3 to be a gene associated with PTC...

Background: Lung cancer is the most common tumor, and has the highest incidence and mortality rates among all malignant tumors. Since stromal cell derived factor-1 (SDF-1) and CXC chemokine receptor 4 (CXCR4) are specific to binding sites, they are more important than other members of the families for tumor invasion and metastasis. We herein aimed to investigate the role of the axis of chemokine SDF-1 and its receptor CXCR4 in the invasion and metastasis of lung cancer. Methods: Sixty clinical non-small cell lung cancer (NSCLC) tissue samples were collected...

Cancer metastasis is a multistep cellular process, which has be confirmed one of mainly causes of cancer associated-death in hepatocellular carcinoma (HCC). MicroRNAs (miRNAs) participate in tumorigenesis function as either tumor suppressor genes or oncogenes. In order to elaborate the critical miRNAs and their targets in HCC, we compared the differential expression of miRNA between HCC tissues and normal tissues. Microarray analysis revealed there were several significantly up-expression miRNAs in HCC, compared to normal solid tissue...

Yes-associated protein (YAP) is a major downstream molecular of the Hippo pathway, which plays important role in cancer development. Netrin-1 conveys oncogenic activity in many types of malignant tumors. However, the downstream signaling of netrin-1 mediating its oncogenic effects in gastric cancer (GC) is not well defined. Here, we aim to investigate the role of netrin-1 in metastasis potential of GC by regulating YAP. In this study, we showed that netrin-1 inhibition significantly decreased migration and invasion abilities of GC cells, while netrin-1 overexpression effectively reversed this effect...

The activation of Notch3 is associated with potential progression of ovarian cancer, tumor invasion, metastasis and chemoresistance, which account for poor prognosis of high grade serous ovarian cancer (HGSOC). However, the underlying mechanisms of Notch3 are not yet very clear. Here we show that SUSD2 is one of Notch3-regulating genes and the elevated protein expression of SUSD2 in HGSOC. We also found that its high expression level was significantly correlated with worse overall survival, early recurrence and lymph nodes metastasis...

Lung cancer is the leading cause of cancer death worldwide. Given that the major threat of cancer is metastasis, delineation of the molecular mechanism underlying it would help devise therapeutic strategies. Transglutaminase 2 (TG2), belonging to the transglutaminase superfamily, is a versatile protein with enzymatic and non-enzymatic functions. It mainly localizes inside the cell, but also appears extracellularly. Recent findings have demonstrated the involvement of TG2 in cancer development. Here we examine the role of TG2 in metastasis of lung cancer using a lung cancer cell line CL1-0 which exhibits low invasiveness, and its invasive subline CL1-5...

Lung adenocarcinoma (LADC)is a general form of non-small cell lung cancer that represents a significant threat to public health worldwide. The 5-year-survival rate for LADC is currently below 15%. The transcription factor KLF15, also called kidney-enriched KLF (KKLF), has been proven to play a role in inhibiting proliferation and diversification of carcinoma cells, including those of the endometrium, pancreas and breast, but the involvement of KLF15 in LADC has not previously been studied. In this study, we compared the in vitro expression of KLF15 in human LADC tissues and adjacent normal lung tissues...

Long non-coding RNA (lncRNA) is emerging as a critical regulator in multiple cancers. Recently, lncRNA PCAT-1 was found to be up-regulated in prostate cancer and hepatocellular carcinoma, exerting oncogenic effects. However, the biological function and regulatory mechanism of PCAT-1 remain unclear in osteosarcoma (OS). In this study, we reported that PCAT-1 expression was also upregulated in OS tissues, and its overexpression was remarkably associated with tumor size, Enneking stage, tumor node metastasis (TNM) stage and metastasis in patients with OS...

In hepatocellular carcinoma (HCC) microenvironment, chemokine receptors have a critical role in tumorigenesis and metastasis. Our previous studies have found that osteopontin (OPN) is a promoter for HCC metastasis. However, the role of chemokine receptors in OPN-induced HCC metastasis still remains unclear. In this study, we demonstrate that OPN is dramatically elevated in HCC tissues with metastasis and high expression of OPN correlates with poorer overall survival and higher recurrence rate. OPN upregulates chemokine receptor expression, migration, invasion, and pulmonary metastasis in HCC...

How to overcome drug resistance and prevent tumor metastasis is key to the success of malignant tumor therapy. In this paper, ADH-1 peptide-modified liposomes (A-LP) have been successfully constructed for restoring chemosensitivity and suppressing cancer cell migration. With a particle size of about 90 nm, this functionalized nanocarrier was loaded with fluorescent probe or paclitaxel (PTX). Cellular uptake studies showed that A-LP facilitated the delivery of anticancer drug to tumor cells undergoing EMT...

Metastasis is the cause of most (>90%) cancer deaths and currently lacks effective treatments. Approaches to understanding the biological process, unraveling the most effective molecular target(s), and implementing nanotechnology to increase the therapeutic index are expected to facilitate cancer therapy against metastasis. Here, we demonstrate the potential advantages of bringing these three approaches together through the rational design of a small interfering RNA (siRNA) that targets p70S6K in cancer stem cells (CSCs) in combination with dendrimer nanotechnology-based siRNA delivery...

Ectopic expression of netrin-1 has been validated in several cancers including non-small cell lung cancer (NSCLC). Recent research confirms the critical role of netrin-1 in NSCLC growth and its prognostic value. Unfortunately, its contribution in NSCLC metastasis remains elusive. Here, netrin-1 had relatively high expression in NSCLC tissues and cells, especially in high metastatic groups. Notably, netrin-1 overexpression aggravated the malignant metastatic behavior of NSCLC cells, including cell invasion, migration, and vasculogenic mimicry (VM), whereas netrin-1 depression reversely dampened the metastatic potential...
